Before what appears to be their inevitable breakup, the 49ers have broken bread with Alex Smith.On Thursday at the NFL combine in Indianapolis, general manager Trent Baalke said he had dinner with Smith and his wife, Elizabeth, shortly after the Super Bowl to discuss the quarterback’s future.

It’s widely expected the 49ers will attempt to trade Smith, whose base salary of $7.5 million would become guaranteed if he remains on the roster April 1. Smith, presumably, would prefer to be released, which would give him flexibility in determining his next team.

“We had a great meal,” Baalke said. “We had a great discussion. I can’t say enough good things. And I think if you ask anyone in our organization they would say the same thing: He is a pro’s pro. And I have nothing but great respect for him, his family, and we’re certainly going to do everything in our power to make the best decision for everyone involved.”

While a parting of the ways appears likely, coach Jim Harbaugh has mentioned the possibility of keeping the eight-year veteran in 2013. Of course, floating such a notion could increase the 49ers’ odds of pulling off a trade: If teams believe the 49ers have no intention of keeping Smith, they could simply wait for him to be released.

“We’re going to look at all options available,” Baalke said. “Are we going to trade him for sure? No, that hasn’t been decided.”

Jenkins to join Kaepernick: According to his agent, Jonathan Perzley, wide receiver A.J. Jenkins will begin training with quarterback Colin Kaepernick on Sunday at CES Performance in Duluth, Ga.

Kaepernick began training at the facility Feb. 12, and has been joined by 49ers wide receivers Ricardo Lockette and Chad Hall, who grew up in the state.

On the heels of Jenkins’ zero-catch rookie season, some fans have grumbled on social media that the 2012 first-round pick had yet to begin working with Kaepernick after pledging to do so following the Super Bowl. In May, Jerry Rice had offered, via Twitter, to work out with Jenkins, but the pair never connected.

Of course, the matter of with whom Jenkins trains – and when he does it – wouldn’t be a talking point if not for his forgettable first season. Jenkins played 37 snaps and dropped the only pass thrown his way.
